FURNACE, RANGE, OR STOVE DOOR.

SPECIFICATION forming part of Letters Patent No. 562,511, dated June 23,1896.

Application filed January 3, 1896. Serial No. 574,224. (No model.)

To to whom it may concern.-

Be it known that I, JOHN E. DAVIS, a citizen of the United States,residing at Conway, in the county of Carroll and State of New Hampshire,have invented a new and useful Improvement in Furnace, Range, or StoveDoors, of which the following is a full, clear,

and exact description, reference being had to the accompanying drawings,forming apart of this specification, inexplaining its nature.

The invention relates to a door especially adapted for an oven door forranges and stoves, and which comprises a casting having an aperturewhich is covered by a glass plate held in or opposite the aperture bythe sections of the lining of tin with which ovendoors are ordinarilyprovided.

Referring to the drawings, Figure 1 is a View in rear elevation of anoven-door having the features of my invention; Fig. 2 is a view inhorizontal section upon the dotted line a: a: of Fig. 1; and Fig. 3 is adetail View in section, enlarged.

A represents the door of cast-iron. It has the aperture a, which may beof anydesired size, and it has attached to its inner surface the lininga of tin. This lining is provided with an aperture a corresponding insize with the aperture 0:, and sections a of the lining, about theaperture, are folded back upon the lining, (see Fig. 4,) and then curvedand extended forward, forming the holdingrecesses a for receiving theedge of the glass. These recesses preferably are within the edge of theaperture, and a glass plate is used which is larger than the aperture,the edges extending past the edge of the aperture. This method ofholding the glass is econo1n ical, and is also a safe one, as I haveascertained that it supports the glass plate by its edges Withoutfracturing it, variations in the temperature of the oven not affectingthe holder sufficiently to bring any strain upon the glass, and theholder being of a some what elastic or yielding character.

In the drawings I have represented the lining, and consequently theglass plate, as secured to the door by means of two bolts, one upon eachside of the opening a. Any other desired means of securing the lining, aand with it the glass plate, to the door may, however, be used.

Having thus fully described my invention, I claim and desire to secureby Letters Patent of the United States- 1. The improved door forfurnaces, ranges and stoves herein described, the same comprising aniron casting A having a central aperture a, a sheet-metal lining uponthe innor surface of the door covering the entire inner surface andhaving continuous extensions about said aperture, which are bent orformed to receive and hold a plate of glass upon the inner side of saiddoor, and the said plate of glass of a size to cover said aperture, asand for the purposes described.

2. The combination of the stove-door casting A having a central aperturea, the tin lining a covering its entire inner surface, and havingcontinuous extensions about the aperture which are bent backward uponthe lining and then forward to form holding-recesses on each side of theaperture and a glass plate covering the aperture,the edges of which arecontained in said recesses, as and for the purposes described.
